Some books try to give you copy-and-paste instructions for how to deal with every single system issue that may arise, but How Linux Works actually shows you how the Linux system functions so that you can come up with your own solutions. After a guided tour of filesystems, the boot sequence, system management basics, and networking, author Brian Ward delves into open-ended topics such as development tools, custom kernels, and buying hardware, all from an administrator's point of view. With a mixture of background theory and real-world examples, this book shows both "how" to administer Linux, and "why" each particular technique works, so that you will know how to make Linux work for you.

    Authors Katherine Daniels and Jennifer Davis provide with actionable strategies you can use to engineer sustainable changes in your environment regardless of your level within your organization.

    Team leads usually have little to no idea how to handle people related issues – issues that affect how the morale, quality of work, and overall performance of the team, and of course impacts how easy or hard it is to implement “the new stuff”.Most team leaders are clueless as to how to handle their manager giving them an impossible due date, a team member reluctant to try anything new, or another team member teaching all the other members practices from 25 years ago that today only hurt the team.Why?No one teaches that to software team leads. Team leads today, in the overwhelming majority of places, are just developers who worked hard and stayed with the company long enough to be promoted. But they have no people or management skills - and those are very painfully needed when you are trying to drive the things you believe in inside an organization that has very little interest in changing.Team leadership is the next big thing that software developers need to conquer, or none of this unit testing, TDD, Agile or Lean thing is going to catch on, except in very small circles, that, by chance, happen to have the right people leading their teams.

    The key, as the authors show, is to integrate regularly and often using continuous integration (CI) practices and techniques. The authors first examine the concept of CI and its practices from the ground up and then move on to explore other effective processes performed by CI systems, such as database integration, testing, inspection, deployment, and feedback. Through more than forty CI-related practices using application examples in different languages, readers learn that CI leads to more rapid software development, produces deployable software at every step in the development lifecycle, and reduces the time between defect introduction and detection, saving time and lowering costs. With successful implementation of CI, developers reduce risks and repetitive manual processes, and teams receive better project visibility. The book covers How to make integration a "non-event" on your software development projects How to reduce the amount of repetitive processes you perform when building your software Practices and techniques for using CI effectively with your teams Reducing the risks of late defect discovery, low-quality software, lack of visibility, and lack of deployable software Assessments of different CI servers and related tools on the market The book's companion Web site, www.integratebutton.com, provides updates and code examples
